Dense packing arrangements

Dense packing arrangements refer to how objects like spheres or particles are efficiently positioned to occupy the maximum possible space without gaps. For example, in materials science, atoms or molecules are arranged in specific patterns—such as face-centered cubic or hexagonal close-packed—that minimize empty space and create stable structures. These arrangements are important for understanding the strength, density, and properties of materials. Essentially, dense packing is the most efficient way to fit shapes together, leaving the least amount of empty space, which influences how materials behave and how tightly they can be packed together.
